RESUMO

BACKGROUND/PURPOSE: Several strategies have been reported for improving the integrity of transurethral resection of bladder tumor (TURBT). However, no standard has been established. Stratified TURBT (SR) is one of protocols for TURBT, wherein exophytic tumors are first resected and retrieved, and tumor bases are then resected. In this study, we aimed to evaluate the outcomes of SR in patients with nonmuscle invasive bladder cancer (NMIBC). METHODS: From January 2012 to December 2017, patients newly diagnosed as having NMIBC with a follow-up period of more than 2 years were enrolled and categorized into SR and conventional TURBT (CR) groups. Propensity score matching at a 2:1 ratio was performed. Outcomes were the detrusor muscle sampling rate, recurrence-free survival (RFS), and progression-free survival (PFS). RESULTS: In total, 205 patients were included in our study. The detrusor muscle sampling rate was higher in the SR group (P = 0.043). After propensity score matching, 162 patients were selected for outcome analysis, with 108 and 54 patients undergoing SR and CR, respectively. Compared with the CR group, the SR group showed a lower recurrence rate (P = 0.015) and better RFS in univariate (P = 0.010) and multivariate (P = 0.006) Cox proportional hazards regression. Progression rate and PFS were not significantly different between the two groups. CONCLUSION: SR results in a higher detrusor muscle sampling rate and better disease outcomes. Our findings suggest that SR is a promising strategy for TURBT in patients with NMIBC.

RESUMO

BACKGROUND: The effect of ambient pollutants on the male reproductive system is controversial. This retrospective study investigated the effect of environmental pollutants on male reproductive health. METHODS: Male patients with primary infertility (n = 282) were identified from a single center between January 2016 and December 2017. Patients were physically examined for the presence of varicocele and for the volume of both testicles. Semen quality was measured in terms of the total sperm count, sperm concentration, and the percentage of sperm cells with motility and normal morphology. Data were acquired on the concentration of ambient pollutants, namely particulate matters of diameter < 2.5 µm, sulfur dioxide (SO2), nitrogen oxides (NOx), and ozone (O3), measured on daily and hourly basis, from the Environmental Protection Administration Executive Yuan, Taiwan. Individual exposure to pollutants was estimated based on the reported residential address of each participant. Statistical analysis indicated the effect of each pollutant on the testicular volume, sex hormone profile, and semen parameters. RESULTS: The mean ± standard deviation of age was 36.7 ± 7.3 years. The average sperm count and concentration were 41.9 million/mL and 34.1 million/mL, respectively. The mean levels of serum testosterone, follicle-stimulating hormone, and luteinizing hormone were 3.57 ± 1.68 ng/mL, 7.59 ± 6.3 IU/L, and 4.68 ± 3.49 IU/L, respectively. According to the multivariate linear regression model, NOx exposure was a risk factor for decreased sperm concentration and motility (p = 0.043 and 0.032). Furthermore, SO2 exposure was negatively associated and testicular volume (p < 0.01). CONCLUSIONS: NO2 and SO2 exposure were negatively associated with the seminal parameter and decreased testicular volume, respectively, in a population of men with infertility. However, additional prospective studies are needed to ascertain the cause-effect relation of current results.

RESUMO

BACKGROUND: Hyperglycemia is associated with series of process leading to oncogenesis. Evidence has shown that diabetes mellitus (DM) seems to be associated with poor prognosis in patients with bladder cancer. However, evidence on the effect of glycemic control on the outcomes of bladder cancer is still limited. In the current study, we aimed to investigate the effect of DM and glycemic control on the prognosis of bladder cancer. METHODS: We conducted a retrospective chart review of a prospective database from January 2012 to December 2017. Patients with newly diagnosed non-muscle invasive bladder cancer (NMIBC) were included. They were classified into the DM and non-DM groups. Prognosis including recurrence rate, progression rate, recurrence-free survival (RFS), and progression-free survival was compared between the two groups. Subgroup analysis of the DM subgroup, in which patients were classified by HbA1C level, was conducted to investigate the effect of glycemic control. RESULTS: A total of 287 patients were included in our study, with 61 patients in the DM group and 226 patients in the non-DM group. No statistically significant difference was found in the prognosis between the DM and non-DM groups. Subgroup analysis revealed higher recurrence rate (P = 0.037) and worse RFS (log-rank P = 0.019) in patients with HbA1C ≥ 7. CONCLUSIONS: DM is not a risk factor for recurrence and progression in patients with NMIBC. However, poor glycemic control is associated with poor prognosis in patients with both DM and NMIBC. Further prospective studies are needed to confirm current results.

RESUMO

BACKGROUND/PURPOSE: Pentosan polysulfate sodium (PPS), a semi-synthetic polysaccharide that adheres to bladder mucosa, is effective in treating interstitial cystitis. We evaluated the clinical benefit of PPS for the prevention of recurrent urinary tract infection (UTI) in women. METHODS: We conducted a multicenter, open-label, prospective, phase II, randomized controlled trial enrolling women with recurrent UTI ≥ 2 times in the past 6 months or ≥ 3 times in the past 12 months. Patients received oral PPS monotherapy for 16 weeks in treatment group. All patients were followed every 28 days until UTI recurrence or up to 112 days. The primary endpoint was the UTI recurrence-free survival. Adverse events were recorded as secondary endpoint. RESULTS: A total of 26 women were eligible for analysis. In the PPS group, none (0%) of the 12 patients had UTI recurrence during the study period. However, 9 (64%) of 14 patients had UTI recurrence in the control group. The UTI recurrence-free survival was significantly higher in the PPS group than in the control group (log-rank test p = 0.0004). One adverse event which led to discontinuation of the trial regimen was regarded as irrelevance of PPS treatment. The limitation was the small number of cases. CONCLUSION: Among women with recurrent UTI, 16-week PPS monotherapy significantly reduced UTI recurrence when compared with the control group.

RESUMO

PURPOSE: To analyze the trifecta outcome (functional, anatomical, and surgical aspects) of surgical reconstruction for ureteral lesions and investigate the factors affecting the success rate of such reconstruction. METHODS: We retrospectively reviewed the data of patients who underwent ureteral reconstruction at our institute between March 2007 and November 2016. Patient profiles, surgical methods, complications, ureteral stenting, laboratory data, and image studies were collected. The trifecta outcome was defined as preserved renal function, no progression of hydronephrosis, and no long-term stenting. The primary endpoint was the percentage of patients who achieved the trifecta outcome. The secondary endpoint was risk factors for trifecta outcome failure. RESULTS: We retrospectively reviewed 178 adult patients who had undergone ureteral reconstruction. The median follow-up period was 37.4 months. In total, 70 (39.3%) patients had iatrogenic ureteral injuries and 108 (60.7%) patients had non-iatrogenic ureteral lesions. Overall, 70% of the patients achieved the trifecta outcome after ureteral reconstruction. A multivariate analysis revealed that risk factors for trifecta failure were malignant diseases [odds ratio (OR) 2.93, p = 0.005], a history of pelvic radiation (OR 3.08, p = 0.032), preoperative estimated glomerular filtration rate < 60 (OR 2.52, p = 0.039), and a type of reconstruction ureteroureterostomy (OR 2.99, p = 0.014). CONCLUSIONS: Trifecta outcome could be used to evaluate the ureteral reconstruction in iatrogenic injury and non-iatrogenic ureteral lesions. This study revealed several risk factors that affected the trifecta outcome.

RESUMO

BACKGROUND/PURPOSE: Prostate specific antigen (PSA) with low specificity that causes unnecessary prostate biopsies increases clinical morbidities, psychological stress, and medical expenses. We aimed to test the accuracy and cutoff value of Prostate Health Index (PHI) in men for prostate cancer detection. METHODS: We prospectively enrolled 213 men who underwent prostate biopsy with PSA≦10 ng/ml or abnormal findings on digital rectal examination. Total PSA (tPSA), free PSA (fPSA) and p2PSA levels were measured by serum samples before prostate biopsy. PHI was calculated as (p2PSA/fPSA) × âˆštPSA. Multivariable logistic regression analyses were used to predict the risk of cancer and detect clinically significant prostate cancer. RESULTS: 33 (27.0%) patients were confirmed with the diagnoses of prostate cancer by prostate biopsy. The levels of p2PSA, %p2PSA, and PHI showed statistically significant differences between prostate cancer patients and non-cancer patients. %p2PSA and PHI had the highest area under the receiver operating characteristic curve (AUC) of 0.723 and 0.772 (both p < 0.001), respectively, predicting cancer detection at biopsy than other predictors (tPSA, fPSA, %fPSA, and PSA density (AUC: 0.544, 0.538, 0.593, and 0.664, respectively). In multivariable logistic regression, %p2PSA had a statistical significant odds ratio 8.51 (p = 0.003) and PHI had an odds ratio with marginal significance 4.18 (p = 0.06). CONCLUSION: %p2PSA and PHI increased the diagnostic accuracy with significantly greater sensitivity and specificity than tPSA. We determined an optimal cut-off value of PHI among Taiwanese population. These findings support the usefulness in the decisional process of prostate biopsy.

RESUMO

Trichostatin A (TSA), an antifungal antibiotic derived from Streptomyces, inhibits mammalian histone deacetylases, and especially, selectively inhibits class I and II histone deacetylase (HDAC) families of enzymes. TSA reportedly elicits an antiproliferative response in multifarious tumors. This study investigated the antitumor effects of TSA alone and in combination with paclitaxel when applied to two high-grade urothelial carcinoma (UC) cell lines (BFTC-905 and BFTC-909). Fluorescence-activated cell sorting, flow cytometry, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium assay were used to assess TSA's cytotoxicity and effects on apoptosis induction. TSA induced synergistic cytotoxicity, when combined with paclitaxel (combination index < 1), resulted in concomitant suppression of paclitaxel-induced activation of phospho-extracellular signal-regulated kinase (ERK) 1/2. A xenograft nude mouse model confirmed that TSA enhances the antitumor effects of paclitaxel. These findings demonstrate that the administration of TSA in combination with paclitaxel elicits a synergistic cytotoxic response. The results of this study indicate that the chemoresistance of UC could be circumvented by combining HDAC inhibitors to target the ERK pathway.

RESUMO

Cisplatin-based chemotherapy is the primary treatment for metastatic bladder urothelial carcinoma (UC). Most patients inevitably encounter drug resistance and resultant disease relapse. Reduced apoptosis plays a critical role in chemoresistance. Trifluoperazine (TFP), an antipsychotic agent, has demonstrated antitumor effects on various cancers. This study investigated the efficacy of TFP in inhibiting cisplatin-resistant bladder UC and explored the underlying mechanism. Our results revealed that cisplatin-resistant UC cells (T24/R) upregulated the antiapoptotic factor, B-cell lymphoma-extra large (Bcl-xL). Knockdown of Bcl-xL by siRNA resensitized cisplatin-resistant cells to the cisplatin cytotoxic effect. TFP (10-45 µM) alone elicited dose-dependent cytotoxicity, apoptosis, and G0/G1 arrest on T24/R cells. Co-treatment of TFP potentiated cisplatin-induced cytotoxicity in T24/R cells. The phenomenon that TFP alleviated cisplatin resistance to T24/R was accompanied with concurrent suppression of Bcl-xL. In vivo models confirmed that TFP alone effectively suppressed the T24/R xenograft in nude mice. TFP co-treatment enhanced the antitumor effect of cisplatin on the T24/R xenograft. Our results demonstrated that TFP effectively inhibited cisplatin-resistant UCs and circumvented cisplatin resistance with concurrent Bcl-xL downregulation. These findings provide a promising insight to develop a therapeutic strategy for chemoresistant UCs.

RESUMO

The prostate is an androgen-sensitive organ that needs proper androgen/androgen receptor (AR) signals for normal development. The progression of prostate diseases, including benign prostate hyperplasia (BPH) and prostate cancer (PCa), also needs proper androgen/AR signals. Tissue recombination studies report that stromal, but not epithelial, AR plays more critical roles via the mesenchymal-epithelial interactions to influence the early process of prostate development. However, in BPH and PCa, much more attention has been focused on epithelial AR roles. However, accumulating evidence indicates that stromal AR is also irreplaceable and plays critical roles in prostate disease progression. Herein, we summarize the roles of stromal AR in the development of normal prostate, BPH, and PCa, with evidence from the recent results of in vitro cell line studies, tissue recombination experiments, and AR knockout animal models. Current evidence suggests that stromal AR may play positive roles to promote BPH and PCa progression, and targeting stromal AR selectively with AR degradation enhancer, ASC-J9, may allow development of better therapies with fewer adverse effects to battle BPH and PCa.

RESUMO

PURPOSE: To evaluate the effectiveness of presence of desmopressin in treating primary enuresis (PE) for children with attention deficit-hyperactivity disorder (ADHD) symptoms. MATERIALS AND METHODS: Children aged from 5 to 12 years with the chief complaint of PE treated with desmopressin were enrolled in pediatric urology clinics. The parent-reported SNAP-IV questionnaire was used to evaluate ADHD symptoms (cut-off value: 90th percentile). Voiding symptoms were assessed by the Dysfunctional Voiding Scoring System (DVSS) questionnaire. The responses to desmopressin were analyzed in children with and without ADHD symptoms. RESULTS: The study sample comprised 68 children; 27 (39.7%) presented with ADHD symptoms and 41 (60.3%) with non-ADHD symptoms. The children collected from a tertiary referral center may explain the high prevalence of ADHD symptoms in the present study. The total DVSS score in the ADHD symptoms group was significantly higher than in the non-ADHD symptoms group (7.72 versus 5.65, P=0.05). In the ADHD symptoms group, there were significantly higher score in the "pee 1-2 times/day" and "can't wait" subscales of DVSS and lower sleep quality based on the Pediatric Sleep Quality questionnaire, as well as significantly lower peak flow rate and voided volume. The responses to desmopressin for enuresis were comparable between children with ADHD and non-ADHD symptoms. CONCLUSIONS: Approximately 39.7% of PE children presented with ADHD symptoms at urologic clinics. PE children with ADHD symptoms had higher risk of daytime LUTS and comparable response to desmopressin treatment for PE. To evaluate ADHD symptoms and daytime voiding symptoms is important in children with PE.

RESUMO

BACKGROUND/PURPOSE: Current guidelines recommend that the optimal timing for cryptorchidism surgery is by the age of 12 months. This study investigated the trend of surgical timing and examined the factors associated with time to surgery for cryptorchidism in Taiwan by using a nationwide, population-based database. METHODS: The present study utilized the Longitudinal Health Insurance Database 2005, a subset of the National Health Insurance Research Database, which contains data on all paid medical benefit claims over the period 1997-2007 for a subset of 1 million beneficiaries randomly drawn from 22.72 million individuals enrolled in the National Health Insurance program in 2005. We analyzed the timing of surgery in boys younger than 18 years with diagnosis of cryptorchidism. RESULTS: We identified 547 boys who underwent surgery under 18 years of age. Approximately 79.2% of study participants received surgery after the age of 12 months. A multivariate analysis showed that several factors were significantly associated with time to surgery: age of the physician making the diagnosis, age of the surgeon performing the surgery, age of the patient at the first diagnosis of cryptorchidism, and number of previous clinic visits with the diagnosis of cryptorchidism and urbanization level of the patient's residence. CONCLUSION: A surprisingly high rate (79.2%) of all study participants underwent surgery beyond the optimal timing. Certain doctor and patient factors were associated with time to cryptorchidism surgery. Improving the alertness and education of parents and specialists may lead to earlier surgeries.

RESUMO

PURPOSE: We investigated the epidemiology of upper urinary tract stone disease in Taiwan using a nationwide, population based database. MATERIALS AND METHODS: This study was based on the National Health Insurance Research Database of Taiwan, which contains data on all medical beneficiary claims from 22.72 million enrollees, accounting for almost 99% of the Taiwanese population. The Longitudinal Health Insurance Database 2005, a subset of the National Health Insurance Research Database, contains data on all medical benefit claims from 1997 through 2010 for a subset of 1 million beneficiaries randomly sampled from the 2005 enrollment file. For epidemiological analysis we selected subjects whose claims records included the diagnosis of upper urinary tract urolithiasis. RESULTS: The age adjusted rate of medical care visits for upper urinary tract urolithiasis decreased by 6.5% from 1,367/100,000 subjects in 1998 to 1,278/100,000 in 2010. There was a significantly decreasing trend during the 13-year period in visits from female and all subjects (r(2) = 0.86, p = 0.001 and r(2) = 0.52, p = 0.005, respectively). In contrast, an increasing trend was noted for male subjects (r(2) = 0.45, p = 0.012). The age adjusted prevalence in 2010 was 9.01%, 5.79% and 7.38% in male, female and all subjects, respectively. The overall recurrence rate at 1 and 5 years was 6.12% and 34.71%, respectively. Male subjects had a higher recurrence rate than female subjects. CONCLUSIONS: Our study provides important information on the epidemiology of upper urinary tract stone disease in Taiwan, helping to quantify the burden of urolithiasis and establish strategies to decrease the risk of urolithiasis.

RESUMO

Squamous metaplasia (SQM) is a specific phenotype in response to oestrogen in the prostate and oestrogen receptor (ER) α is required to mediate this response. Previous studies utilizing tissue recombination with seminal vesicle (SV) mesenchyme and prostatic ductal tips from wild type and ERαKO mice suggested that both epithelial and stromal ERα are necessary for SQM. However, tissue recombination is conducted in the renal capsule of immune-deficient mice, in which the microenvironment is different from normal prostate microenvironment in the intact mice. Furthermore, whether the requirement of stromal ERα in the SV for developing SQM is the same as in the prostate is unknown. Therefore, there is a clear need to evaluate the respective roles of ERα in prostate epithelial versus stromal compartments in the intact mouse. Here we generated a mouse model that has selectively lost ERα in either stromal (FSP-ERαKO) or epithelial prostate cells (pes-ERαKO) to determine the requirements of ERα for oestrogen-stimulated prostate proliferation and SQM. Our results indicated that FSP-ERαKO prostates develop full and uniform SQM, which suggests that loss of the majority (~65%) of stromal ERα will not influence oestrogen-mediated SQM. In contrast, loss of epithelial ERα inhibits oestrogen-mediated prostate growth and SQM evidenced by decreasing cytokertin 10 positive squamous cell stratification and differentiation, by reduced ERα protein expression in SQM compared to wild type mice ERα, and by the presence of normal proliferative activities in the oestrogen-treated pes-ERαKO prostates. These in vivo results suggest that epithelial ERα is required for oestrogen-mediated proliferative response and could be an appropriate target for preventing aberrant oestrogen signalling in the prostate.

RESUMO

AIM: To determine the incidence rate and characteristics in patients with testicular torsion in Taiwan using a nationwide insurance database. METHODS: This study utilizes a subset of national health insurance research database, which contains the data of all paid medical benefit claims over the period 1997-2010 for in 1 000 000 beneficiaries in 2005. We analysed claims data for all male subjects younger than 25 years with the diagnosis of testicular torsion. RESULTS: A total of 86 subjects younger than 25 years with the diagnosis of testicular torsion were included. Among them, 22 (25.6%) underwent orchiectomies and 64 (74.4%) underwent orchiopexies. The estimated incidence of testicular torsion was 3.5 per 100 000 person-years. There are two peaks in the age-specific incidence rates: the first in boys aged 10-14 years (at 7.7 per 100 000 person-years) and the second in male infants aged <1 year (at 7.6 per 100 000 person-years). There was significant difference between orchiectomy and orchiopexy groups in the Insurance fee (p = 0.032). CONCLUSION: The incidence of testicular torsion in Taiwan was similar with previous report in the United States. It is important to improve the medical access to achieve better outcomes of testicular torsion.

RESUMO

BACKGROUND/PURPOSE: Children with attention deficit hyperactivity disorder (ADHD) tend to be more vulnerable to various forms of voiding dysfunction and nocturnal enuresis (NE). We attempt to compare the clinical manifestations and attentional performance between ADHD children with NE and those without NE. METHODS: We consecutively enrolled children diagnosed with ADHD in child and adolescent psychiatric clinics. The questionnaires for evaluation of ADHD symptoms and voiding dysfunction symptoms were administered to all study participants. All participants also received the Test Battery for Attention Performance (TAP) for assessment of attentional function. RESULTS: A total of 53 children were enrolled in this study, comprising 47 boys and six girls. The prevalence rate of NE was 28.3%. Children in the NE group had statistically significant higher dysfunctional voiding symptom score (5.40 ± 3.66 vs.3.16 ± 2.74; p = 0.018) and two subscales of "When I wet myself, my underwear is soaked" (p < 0.001) and "I miss having a bowel movement every day" (p = 0.047). There were no significant differences with regard to all psychiatric evaluations between the NE and non-NE groups. In the TAP test, the NE group showed a significantly shorter reaction time in the domain of inhibitory control, working memory, and auditory sustained attention than the non-NE group. CONCLUSION: Children with ADHD have a high prevalence of NE. ADHD children with NE had a significantly higher dysfunctional voiding symptom score and shorter reaction time in most domains of the TAP test. Further study is needed to discern the impact of NE on the neuropsychological function of ADHD children.

RESUMO

Primary malignancies of female urethral diverticulum are rare. A well-documented female patient with primary clear cell carcinoma of the urethral diverticulum is presented here. A 65-year-old woman presented with frequency and voiding difficulty for 2 months. Physical examination showed a 4-cm mass protruding from anterior vaginal wall. Intravenous urography, magnetic resonance imaging, and cystoscopy showed a polypoid mass in urethral diverticulum. She then underwent anterior exenteration with ileal conduit diversion and urethrectomy. Pathology confirmed the diagnosis of clear cell adenocarcinoma with bladder neck invasion. She had no disease recurrence at 2-year follow-up. Careful clinical examination and image studies are helpful in making the preoperative diagnosis for the rare disease. Early radical surgery can achieve better survival.

RESUMO

We retrospectively evaluated the efficacy of prophylaxis with pipemidic acid and levofloxacin in transrectal ultrasound guided prostate biopsy (TRUSP-Bx). From January 2002 to December 2004, patients receiving oral pipemidic acid 500 mg twice daily for three days with or without a preoperative intravenous cefazolin 1 gm injection comprised group A. Between January 2005 and December 2009, patients receiving oral levofloxacin 500 mg one hour before biopsy comprised group B. We calculated the annual febrile urinary tract infection (fUTI) rates. Patients' characteristics, including age, prophylactic antibiotics, biopsy core numbers, pathologic results, PSA, and the spectrums and susceptibility of pathogens, were also evaluated. A total of 1313 (35.5%) patients belonged to group A, while 2381 (64.5%) patients belonged to group B. Seventy-three patients experienced postoperative infectious complications. There was a significant difference in the fUTI rate between groups A and B (3.7% versus 1.0%, P < 0.001). The yearly fUTI rates varied from 0.6 to 3.9% between 2002 and 2009. Of the 73 patients with fUTI, those receiving levofloxacin prophylaxis were more likely to harbor fluoroquinolone-resistant pathogens (P < 0.001). E. coli was the most common pathogen in both groups. Levofloxacin remains effective and appears superior to pipemidic acid based prophylaxis.

RESUMO

According to the Taiwan Cancer Report, in 2018, prostate cancer was one of the top five cancers reported in men. Each year, many patients with prostate cancer undergo radical prostatectomy (RP) therapy. One of the most common RP complications is erectile dysfunction (ED). Although consensus guidelines for the management of sexual dysfunction after prostate cancer surgery have been developed for many Western and Asian countries, no such clinical practice guidelines have been developed for Taiwan. The consensus opinions expressed in this article were discussed by numerous experienced physicians in Taiwan, based on both existing international guidelines and their individual experiences with clinical trials and providing advice to clinical physicians on how to inform patients of the risk of ED prior to surgery. This review also discusses how recovery and rehabilitation may be affected by socioeconomic status, the existence of an intimate relationship, comorbidities, or the need for cancer adjuvant therapy and how to determine rehabilitation goals and provide appropriate treatments to assist in the recovery of both short- and long-term sexual function.

RESUMO

Introduction: Penile reconstructive and prosthetic surgery remains a highly specialized field where potential complications can be devastating, and unrealistic patient expectations can often be difficult to manage. Furthermore, surgical practice can vary depending on locoregional expertise and sociocultural factors. Methods: The Asia Pacific Society of Sexual Medicine (APSSM) panel of experts reviewed contemporary evidence regarding penile reconstructive and prosthetic surgery with an emphasis on key issues relevant to the Asia-Pacific (AP) region and developed a consensus statement and set of clinical practice recommendations on behalf of the APSSM. The Medline and EMBASE databases were searched using the following terms: "penile prosthesis implant," "Peyronie's disease," "penile lengthening," "penile augmentation," "penile enlargement," "buried penis," "penile disorders," "penile trauma," "transgender," and "penile reconstruction" between January 2001 and June 2022. A modified Delphi method was undertaken, and the panel evaluated, agreed, and provided consensus statements on clinically relevant penile reconstructive and prosthetic surgery, namely (1) penile prosthesis implantation, (2) Peyronie's disease, (3) penile trauma, (4) gender-affirming (phalloplasty) surgery, and (5) penile esthetic (length and/or girth enlargement) surgery. Main outcome measures: Outcomes were specific statements and clinical recommendations according to the Oxford Centre for Evidence-Based Medicine, and if clinical evidence is lacking, a consensus agreement is adopted. The panel provided statements on clinical aspects of surgical management in penile reconstructive and prosthetic surgery. Results: There is a variation in surgical algorithms in patients based on sociocultural characteristics and the availability of local resources. Performing preoperative counseling and obtaining adequate informed consent are paramount and should be conducted to discuss various treatment options, including the pros and cons of each surgical intervention. Patients should be provided with information regarding potential complications related to surgery, and strict adherence to safe surgical principles, preoperative optimization of medical comorbidities and stringent postoperative care are important to improve patient satisfaction rates. For complex patients, surgical intervention should ideally be referred and performed by expert high-volume surgeons to maximize clinical outcomes. Clinical implications: Due to the uneven distribution of surgical access and expertise across the AP region, development of relevant comprehensive surgical protocols and regular training programs is desirable. Strengths and Limitations: This consensus statement covers comprehensive penile reconstructive and prosthetic surgery topics and is endorsed by the APSSM. The variations in surgical algorithms and lack of sufficient high-level evidence in these areas could be stated as a limitation. Conclusion: This APSSM consensus statement provides clinical recommendations on the surgical management of various penile reconstructive and prosthetic surgeries. The APSSM advocates for surgeons in AP to individualize surgical options based on patient condition(s) and needs, surgeon expertise, and local resources.

RESUMO

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients' factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: "low libido", "erectile dysfunction", "ejaculatory dysfunction", "premature ejaculation", "retrograde ejaculation", "delayed ejaculation", "anejaculation", and "orgasmic dysfunction" between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socio-economic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient's individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.
